Bootloader 2c.7cSupport

I just replaced and got a brand new battery. I spent over 3 hours searching in the web as to how to re-programming my cellphone. here's what I downloaded to my pc which I thought is require:
1. Motorola Device Manager
2. RSD lite 4.9
3. SPRecovery_ESE81.sbf
4. Motorola USB/PC drivers
5. Java Platform SE
6. Android SDK Manager

Why can't I re-program my cellphone thru my PC with all this?
Is there an easy way that has all the necessary software to jumpstart my cellphone?
Appreciate your kind help and quick response. Thank you in advance.
